Yeah .... Funny, I once looked at dba.se and decided it brought back bad memories.
I am officially certified as a "Sybase SQL Developer" (got the certificate, and all). I do know databases (though I was never actually a formal DBA since II never carried the pager .... ;-)
@rolfl @Jamal that was my fault. I didn't think that question belonged here. and i gained rep in the move and started with a clean slate over there....lol
@rolfl Ah, THAT'S how to get the Hello World hat! Perhaps I should post a question on Christianity which I have been thinking about for a while... But unfortunately, that wouldn't help on my leaderboard here on CR.
Needless to say, I'm going back through C++ questions, mainly for voting. I've already found one non-answer from 2011, and I came across one of my 0-score answers.
@rolfl he has his "special" towel - I don't know, it just seems to be a "don't touch my hair" thing. They haven't had their first haircut yet, I wonder how that's going to go...
(first haircut for my son - freaked about the 'trimmer' being used around his side-burns/ears. Finally convinced him it was going to be OK, and then the damn hairdresser knicks his ear-lobe and h'es bleeding, screaming, and took years to get that machine used again.
(in the hairdresser's defense, he was squirrelling like a cat about to have a bath).
I wonder whether I should 'blow the minds' of the dba.se folk. I am on the second-row of their users page for the week:
Can we close an older question as a duplicate of a newer question from the same user or it has to be the other way around? The older question is a rotting zombie:
I am trying to capture screenshots as fast as possible from when it's displayed, meaning that I want the latency to be minimal.
Currently, I am using user32.dll to capture a window. So, if I have a game, I capture that window along with borders and everything. It's very fast, but I wonder if ho...
I have done some tests of my code, which I got help to improve here before.
The code simply takes a screenshot of selected process window, encode it to jpeg(if I want) and save it to a memorystream and return it (need to that to send it).
So my test which I got help with to do, simply runs the c...

@200_success we'd need to test for zygocity, the placenta analysis wasn't conclusive (there's still a chance they could be identical twins) - they do look alike, but to me they're quite different.. but not everyone agrees :)
@200_success the twins? oh, the questions.. perhaps.
Woah: 57,469 users from around the network have earned a total of 137,401 hats... and I'm #22??!!
@200_success it's not clear whether it's only about game.. you think GameDev could answer it?
@retailcoder The User32.dll question is marginally on-topic for GameDev. The other question says it's for desktop remoting, which is clearly not for GameDev.
Repeated screen captures seems like a crazy way to implement remote desktop, though. I think it's an XY problem.
It has come to my attention that Spam Review, a site that has serious potential to help Stack Exchange people and spammers worldwide improve their spam, has been closed. This seems like a serious bug to me.

@retailcoder On further thought, I think we should just leave the screen capture questions alone. Update 4 settled on BitBlt() anyway. Not all questions are answerable, and that's OK.

@retailcoder You could post an answer that says that your code is already optimal, and if it's still not fast enough, use a different approach (e.g. install an instrumented display driver) or get a faster machine. I don't feel qualified enough in that domain to post such an answer myself.

Both questions are too old for migration, so that possibility is out. It's also hard to tell if they're dupes (not exact dupes, obviously), and they may not be. Other than that, they look on-topic enough here. As they have been around awhile without much attention, possibly due to the complexi...

@Malachi the badge is awarded on score, not rep. That way both question and answer upvotes count equally. (and downvotes). I am approaching silver for java, and bronze for optimization:
@Malachi as for the dba downvote, DBA and database people in general are, by design, very pedantic and structured. My guess is that your 'easy' style is not suited to the DBA crowd, and thus gets a negative response. It's a result of the question migrating to a place where the viewers are more critical than here.
DBA's do not have a sense of humor .... trust me, I know.
@syb0rg it's your idea that shows up in the newsletter; this week, @rolfl's Sudoku Solver was featured through the posts of @SimonAndréForsberg, @GarethRees', and @tomdemuyt.

1. Does my question contain code? No => off-topic. I'm not denying the effort you put into your question, but rule#1 cannot bend, your question has to include the code you want peer reviewed.

@Jamal what do you mean by "and this next close was automatic."
was that just because they tried to ask a question here that would have been migrated there?
@tomdemuyt I removed the javascript tag. it's not about Javascript really. if they tried to do both I would suggest to the OP to separate it into two questions, optimize the JS first then translate to Lua then post the Lua optimization question.

@PhilFromHeck Well, I have to admit that I've got no idea what design you're trying to code. Why don't you post a question on Stack Overflow with a picture showing what you want, and a minimal HTML+CSS example to show what you've got?
@PhilFromHeck You will also want to research modernizr.com – a JS library that can tell you if certain features are available (better than remembering which version of IE can do what, and what browser IceWeasel was again)
Why not just pull the value from the Dictionary? If it's an invalid value, you'll have your exception for free! :) — retailcoder2 hours ago
Because then you get some stupid, unintelligible exception message. This way you can actually throw somethign useful. — jessehouwing54 mins ago
The KeyNotFoundException would (should?) never be thrown in production code, so a custom exception makes no sense to me. "The given key was not present in the dictionary" says exactly what's going on, and the stack trace will point to Dictionary.GetValue in the very method you're doing that, which is all you need to debug the issue. I don't see the added value of a custom exception message in this case, it's overkill. — retailcoder1 min ago

@retailcoder Generally, encapsulation is considered to be a good thing. On sites other than Code Review, pragmatism would also have a place (I write Perl: It's ugly to look at, but beautiful that it works).
@Nobody right, but in this case the dictionary is replacing a switch block over a finite set of enum values - if the exception is thrown it's because there's a serious bug, clearly wouldn't be thrown in production.
I mean the exception would only be thrown in the dev's IDE.
Is it OK if I write a question and instead of putting the code here on Code Review, I include a link to github/pastebin/other similar site?
(Seeing as there wasn't a similar topic like this here on meta, I thought it was about time to post one)
@Nobody if I have an enum with values { A, B, C } and you write code that fills up a dictionary with {A, B, C} as keys, how is it possible that D appears in production? If D isn't in the valid enum values, the code won't even build...

@amon In one way, yes. But having a meta question for it seems useful, and also easier to link to some times. And could also be a place for adding comments/questions/further discussion about it
@Nobody I'd rather have the app blow up with a funky exception message if my messed-up code inadvertently ended up in production, than telling the user "We're sorry, something unexpected has just happened that wasn't supposed to happen, please take a screenshot and email your help desk!"
@retailcoder: another scenario that goes in the same direction would be to distinguish further and emit different exceptions to react in another way higher up the call tree
@Malachi maybe a little... I just don't seem to get how one could write C# code that puts an enum type as a dictionary key, and then manage to build that C# code while trying to fetch a non-existent enum value from that dictionary. Seems to ignore the language's type-safety.
@retailcoder: The case in question is hardly big enough to justify the extra work of a new exception class. however, it is not easy to draw a line when to start and as I said such code can get out of hand very fast
Nothing to do with the Security of the Functions
what you should do is create one function that will accept a parameter of encrypt or decrypt most of the information that you are using in both functions is duplicated.
function encryptOrDecrypt($mprhase, $crypt) {
$MASTERKEY = "KEY PHRASE!"...
@PhilFromHeck remind me what we are talking about Phil
@amon are you talking about the parameter? I just took the OP's code and altered it a little bit, the parameter could be anything they want it to be, like an Integer or a boolean.
@amon thank you I am enjoying the link. both you and @Nobody have helped me to see the code a little differently today.
Code is such a complex thing.
